Zhu Guangqian’s poems and famous quotes for the fourth grade are as follows:

1. Interest must be cultivated in youth. After the normal season, it will wither. I acknowledge that genetic and environmental influences are significant, but I believe that neither of them fully explains genius. It is common people's misunderstanding to regard pleasure as beauty and association as beauty. In addition, there is another misunderstanding held by scholars, which is to regard textual research and criticism as appreciation.

2. Learning and career can only be regarded as the second thing in life. The first thing in life is life. What I call "life" is "enjoyment", "appreciation" and "cultivation of vitality". If you forget about life for the sake of knowledge and career, that kind of knowledge and career will lose their true meaning and value in life. Many arts apply rules and rhythms, and the psychological effects of rules and rhythms are based on this unintentional anticipation.
